Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511530, here are decompositions:

7 + 511523 = 511530
11 + 511519 = 511530
23 + 511507 = 511530
43 + 511487 = 511530
53 + 511477 = 511530
67 + 511463 = 511530
73 + 511457 = 511530
83 + 511447 = 511530

Showing the first eight; more decompositions exist.
